Abstract
Description
15 20 25 30 35 508 398 2 Enligt ytterligare en variant av uppfinningen sträcker sig det mjuka nonwovenmaterialet även över absorptionskroppen innanför toppskiktet samt uppvisar delar som sträcker sig utanför absorptionskroppen och är förenade med motsvarande utanför absorptionskroppen sig sträckande delar av botten- skiktet. Man får härigenom ett dubbelt ytmaterial, ett lami- nat. Genom den uppfinningsenliga infästningen av toppskiktet längs sidokanterna medges att detta i övrigt endast i liten grad eller inte alls behöver sammanbindas med det inre topp- skiktet, vilket gör att det dubbla ytmaterialet enligt upp- finningen är lenare än ett på konventionellt sätt laminerat dubbelt ytmaterial. Genom den kraftiga förankring, som si- doinfästningen av toppskiktet innebär undvikes vidare risken för "delaminering", dvs. att toppskiktet och det innanför- liggande nonwovenmaterialet frigöres från varandra. According to a further variant of the invention, the soft nonwoven material also extends over the absorbent body inside the top layer and has parts which extend outside the absorbent body and are connected to corresponding parts of the bottom layer extending outside the absorbent body. This gives a double surface material, a laminate. The inventive attachment of the top layer along the side edges allows it to otherwise only to a small extent or not at all be connected to the inner top layer, which means that the double surface material according to the invention is smoother than a double surface material laminated in a conventional manner. Due to the strong anchoring that the side attachment of the top layer entails, the risk of "delamination" is further avoided, ie. that the top layer and the inner nonwoven material are released from each other.
Uppfinningen kommer i det följande att närmare beskrivas med hänvisning till några på bifogade ritning visade utföringsex- empel, där: fig. 1 schematiskt visar en utföringsform av en dambinda enligt uppfinningen i en vy ovanifrån, fig. 2 visar ett snitt längs linjen II-II i fig. 1, fig. 3 i tvärsnitt visar en variant av dambindan i fig. 1, och fig. 4 i tvärsnitt visar ytterligare en variant av en dam- binda enligt uppfinningen.The invention will be described in more detail below with reference to some exemplary embodiments shown in the accompanying drawing, in which: Fig. 1 schematically shows an embodiment of a sanitary napkin according to the invention in a top view, Fig. 2 shows a section along the line II-II in Fig. 1, Fig. 3 shows in cross section a variant of the sanitary napkin in Fig. 1, and Fig. 4 in cross section shows another variant of a sanitary napkin according to the invention.
I fig. 1 och 2 visas en dambinda enligt en utföringsform av uppfinningen. Denna dambinda innefattar på konventionellt sätt en absorptionskropp 1 innesluten mellan ett vätskegenom- släppligt skikt 2, vilket lämpligen består av ett mjukt nonwovenmaterial och vid bindans användning är vänt mot användarens kropp, och ett vätskeogenomträngligt bottenskikt 3. Skikten 2, 3 har delar, vilka sträcker sig utanför absorp- tionskroppen, och skikten är förenade med varandra i dessa 10 15 20 25 30 35 508 398 delar. Bottenskiktet 3 består av ett lämpligt plastmaterial, t.ex. polyetenplast. Absorptionskroppen är företrädesvis uppbyggd av fluffmassa med eller utan inblandning av s.k. superabsorbenter. 3 Andra kända material för absorptionskropp samt topp- och bottenskikt kan naturligtvis utnyttjas inom ramen för upp- finningen.Figures 1 and 2 show a sanitary napkin according to an embodiment of the invention. This sanitary napkin conventionally comprises an absorbent body 1 enclosed between a liquid-permeable layer 2, which suitably consists of a soft nonwoven material and when the napkin is used facing the user's body, and a liquid-impermeable bottom layer 3. The layers 2, 3 have parts which extend outside the absorbent body, and the layers are joined together in these 10 15 20 25 30 35 508 398 parts. The bottom layer 3 consists of a suitable plastic material, e.g. polyethylene plastic. The absorbent body is preferably made up of fluff mass with or without admixture of so-called superabsorbents. Other known materials for absorbent body as well as top and bottom layers can of course be used within the scope of the invention.
Enligt de på ritningen visade utföringsexemplen är ett väts- kegenomsläppligt toppskikt 4 i form av ett nät eller liknande placerat utanpå nonwovenskiktet 2 över den del av detta skikt, som övertäcker absorptionskroppens 1 ovansida, dvs. den sida hos absorptionskroppen som vid bindans användning är vänd mot användaren. Nätet 4 är tillverkat av ett icke-absor- berande material. Materialet är företrädesvis hydrofilt åtminstone på den sida, som vid bindans användning är vänd mot användaren, för att vätska lätt skall kunna strömma igenom materialet. Den motsatta sidan kan eventuellt vara hydrofob. Om nätets öppningsarea är tillräckligt stor kan även helt hydrofoba material användas. Lämpliga material för nätet är syntetmaterial, t.ex. polypropen eller polyeten. I stället för ett nät kan en perforerad, plan eller tredimen- sionell plastfilm av t.ex. polypropen eller polyeten använ- das. Hålen bör företrädesvis ha en diameter av 0,1 till 3 mm.According to the embodiments shown in the drawing, a liquid-permeable top layer 4 in the form of a net or the like is placed on top of the nonwoven layer 2 over the part of this layer which covers the upper side of the absorption body 1, i.e. the side of the absorbent body which, when used, is facing the user. The net 4 is made of a non-absorbent material. The material is preferably hydrophilic at least on the side which, when the napkin is used, faces the user, so that liquid can easily flow through the material. The opposite side may be hydrophobic. If the opening area of the net is large enough, even completely hydrophobic materials can be used. Suitable materials for the net are synthetic materials, e.g. polypropylene or polyethylene. Instead of a net, a perforated, flat or three-dimensional plastic film of e.g. polypropylene or polyethylene is used. The holes should preferably have a diameter of 0.1 to 3 mm.
Det yttre toppskiktet 4 kan även vara ett nonwovenmaterial baserat på polymera fibrer, t.ex. polypropen eller polyeten, dtex 1-10. Genom att det yttre toppskiktet 4 slutar en bit innanför bindans sidokanter erhålles en materialinbesparing.The outer topsheet 4 may also be a nonwoven material based on polymeric fibers, e.g. polypropylene or polyethylene, dtex 1-10. By the outer top layer 4 ending a bit inside the side edges of the napkin, a material saving is obtained.
Nätet 4 är längs sina längsgående kanter fäst till det inre toppskiktet, nonwovenskiktet 2 genom veck 5, 6 i detta. Dessa veck har vikts över de längsgående sidokanterna av nätet 4 och sedan förbundits med dessa och med den mot absorptions- kroppens 1 ovansida anliggande delen av det inre toppskiktet 2. Denna förbindning kan åstadkommas med hjälp av limsträngar 7, 8, såsom indikeras i fig. 2, men även värme- eller ultra- ljudssvetsning kan användas. På så sätt uppnås en mycket 10 15 20 25 30 35 508 398 4 stark infästning av nätet 4 samtidigt som risken för att nätkanterna skall skava mot användarens hud elimineras.The net 4 is attached along its longitudinal edges to the inner top layer, the nonwoven layer 2 through folds 5, 6 therein. These folds have been folded over the longitudinal side edges of the net 4 and then connected to them and to the part of the inner top layer 2 abutting against the upper side of the absorbent body 1. This connection can be effected by means of adhesive strands 7, 8, as indicated in fig. 2, but also heat or ultrasonic welding can be used. In this way a very strong attachment of the net 4 is achieved at the same time as the risk of the net edges rubbing against the user's skin is eliminated.
I den i fig. 1 och 2 visade utföringsformen är de utanför absorptionskroppens 1 kortändar utskjutande delarna av bot- tenskiktet 3 och nonwovenskiktet 2, vilka som tidigare nämnts är förbundna med varandra, vikta över absorptionskrcnpen 1 och kortändarna av nätet 4 och fästa till nätet och under- liggande delar av nonwovenskiktet 2. Om man vill undvika att det vätskeogenomträngliga bottenskiktet 3 sträcker sig över den mot användaren vända sidan av dambindan kan bottenskiktet 3 dimensioneras så att det är kortare än det inre toppskiktet 2 och vid invikningen endast övertäcker sidokanterna av absorptionskroppens 1 kortsidor, medan det längre nonwoven- skiktet 2 ges en sådan utsträckning att det även övertäcker kortsidekanten av nätet 4. Man kan även tänka sig att utforma nonwovenskiktet 2 med tvärgående veck analoga med de längs- gående vecken 5, 6. Det är naturligtvis även möjligt att använda separata band av hudvänligt material för att över- täcka kortsidekanterna hos nätet 4.In the embodiment shown in Figs. 1 and 2, the parts of the bottom layer 3 and the nonwoven layer 2 projecting outside the short ends of the absorbent body 1, which as previously mentioned are connected to each other, are folded over the absorbent body 1 and the short ends of the net 4 and attached to the net and underlying parts of the nonwoven layer 2. If it is desired to avoid that the liquid-impermeable bottom layer 3 extends over the user-facing side of the sanitary napkin, the bottom layer 3 can be dimensioned so that it is shorter than the inner top layer 2 and at fold only covers the side edges of the absorbent body 1. short sides, while the longer nonwoven layer 2 is given such an extent that it also covers the short side edge of the net 4. It is also conceivable to design the nonwoven layer 2 with transverse folds analogous to the longitudinal folds 5, 6. It is of course also possible to use separate strips of skin-friendly material to cover the short side edges of the net 4.
Genom att nätet 4 är starkt förankrat till nonwovenskiktet 2 längs sidokanterna behövs endast en förhållandevis svag förbindning mellan nätet och nonwovenskiktet i jämförelse med ett rent laminat. Lenheten hos ytskiktet är generellt sett beroende på hur hårt de båda skikten 2 och 4 är bundna till varandra på så sätt att en svagare förbindelse ger en lenare yta. Även om det föredrages att förbinda nätet 4 med det under- liggande inre toppskiktet 2 på ovannämnt sätt är detta inte oundgängligen nödvändigt eftersom kanten hos vecken 5, 6 verkar som barriärer mot sidoläckage. I utföringsformen enligt fig. 3 har denna effekt förstärkts genom att elastik- trådar 9, 10 har lagts in i vecken i utspänt tillstånd och fästs till det inre toppskiktet 2 åtminstone vid sina ändar.Because the net 4 is strongly anchored to the nonwoven layer 2 along the side edges, only a relatively weak connection between the net and the nonwoven layer is needed in comparison with a pure laminate. The smoothness of the surface layer is generally dependent on how tightly the two layers 2 and 4 are bonded to each other in such a way that a weaker connection gives a smoother surface. Although it is preferred to connect the net 4 to the underlying inner top layer 2 in the above-mentioned manner, this is not necessarily necessary since the edge of the folds 5, 6 acts as barriers against side leakage. In the embodiment according to Fig. 3, this effect has been amplified in that elastic threads 9, 10 have been inserted into the folds in the stretched-out state and attached to the inner top layer 2 at least at their ends.
I den vänstra delen av fig. 3 visas konfigurationen hos vecket 5 under tillverkningen av bindan, dvs. när denna hålles plan och utsträckt, medan den högra delen av fig. 3 10 15 20 25 30 35 5038 398 visar konfigurationen av vecket 6 efter att elastiktråden 10 tillåtits dra ihop sig och därmed deformera bindan till krökt 5 form. Genom att Vecken gjorts större än den i fig. l och 2 visade utföringsformen åstadkommes relativt höga vätskebar- riärer. Veckens 5,6 storlek bestämmer således vätskebarríä- rernas höjd.The left part of Fig. 3 shows the configuration of the fold 5 during the manufacture of the napkin, i.e. when this is kept flat and extended, while the right part of Fig. 3 shows the configuration of the fold 6 after the elastic thread 10 has been allowed to contract and thereby deform the napkin into a curved shape. By making the Fold larger than the embodiment shown in Figs. 1 and 2, relatively high liquid barriers are created. The size of the 5.6 fold thus determines the height of the liquid barriers.
Vecken 5,6 kan även vara anordnade utanför absorptionskroppen 1, vilket kan vara lämpligt om de förses med elastiktrådar 9,10. I så fall sträcker sig nätet 4 lite utanför absorp- tionskroppen.The folds 5,6 can also be arranged outside the absorbent body 1, which may be suitable if they are provided with elastic threads 9,10. In this case, the net 4 extends slightly beyond the absorbent body.
Genom att vid bindor enligt fig. 2 och 3 ha dubbla höljes- skikt 2 och 4 ökas avståndet mellan absorptionskroppen 1 och användarens hud. Nonwovenskiktet 2 verkar som ett distans- skikt och kan eventuellt väljas poröst, vilket minskar åter- vätningen. Endast en liten mängd vätska fastnar i nätmaskor- na, vilket är särskilt viktigt vid bindor p.g.a. menstrua- tionsvätskans höga viskositet. Ytan upplevs härigenom både visuellt och känslomässigt som torr.By having double cover layers 2 and 4 with napkins according to Figs. 2 and 3, the distance between the absorbent body 1 and the user's skin is increased. The nonwoven layer 2 acts as a spacer layer and can possibly be selected porous, which reduces rewetting. Only a small amount of liquid gets stuck in the mesh stitches, which is especially important for sanitary napkins due to high viscosity of menstrual fluid. The surface is thus experienced both visually and emotionally as dry.
Bindan enligt det i fig. 4 visade utföringsexemplet uppvisar inte dubbla höljesskikt på ovansidan som i de ovan beskrivna exemplen utan vid denna binda är endast toppskiktets 4 längs- gående sidokanter övertäckta av nonwovenmaterial 2 eller annat mjukt material, vilket på motsvarande sätt som ovan är fäst till utanför absorptionskroppen 1 sig sträckande partier av bottenskiktet 3. Eventuellt kan nonwovenmaterialet 2 vara vikt kring toppskiktets 4 kanter på motsvarande sätt som i fig. 2 och 3, men sluta strax innanför det invíkta partiet.The napkin according to the exemplary embodiment shown in Fig. 4 does not have double cover layers on the upper side as in the examples described above, but in this napkin only the longitudinal side edges of the top layer 4 are covered with nonwoven material 2 or other soft material, which is attached in a corresponding manner as above. to portions of the bottom layer 3 extending outside the absorbent body 1. Optionally, the nonwoven material 2 may be folded around the edges of the top layer 4 in the same manner as in Figs.
En annan möjlighet är att i stället för omvikta partier av nonwovenmaterial 2 använda sig av separata band av hudvänligt material för att övertäcka toppskiktets 4 längsgående sido- kanter.Another possibility is to use instead of folded portions of nonwoven material 2 use separate strips of skin-friendly material to cover the longitudinal side edges of the top layer 4.
Uppfinningen kan naturligtvis även tillämpas på den typ av binda där nonwovenmaterialet sträcker sig runt hela bindan, även utanför det vätskeogenomträngliga bottenskiktet 3. I ett 508 398 6 sådant fall saknar bindan de utanför absorptionskroppen sig sträckande sidokanterna av höljesskikten 2 och 3. Även om uppfinningen är speciellt lämplig för bindor där menstruationsvätskans viskositet och närheten till bindans sidokanter från vätpunkten gör att risken för sidoläckage är särskilt accentuerad kan uppfinningen med fördel även utnytt- jas vid andra typer av absorberande engångsartiklar, såsom inkontinensskydd och blöjor.The invention can of course also be applied to the type of napkin where the nonwoven material extends around the entire napkin, even outside the liquid-impermeable bottom layer 3. In such a case, the napkin lacks the side edges of the casing layers 2 and 3 extending outside the absorbent body. particularly suitable for sanitary napkins where the viscosity of the menstrual fluid and the proximity to the side edges of the sanitary napkin from the wetting point means that the risk of side leakage is particularly accentuated, the invention can also be used with advantage in other types of disposable absorbent articles, such as incontinence guards and diapers.
